• Game Technologies: DirectX, XNA, XACT, etc. Custom blending

  I need an alpha blend, which blends the alpha as well. I need this on systems which might not have seperate alpha blend, so I was considering doing it in a pixel shader. It would be easy to put the blend into ordinary code, but... I can not, as far as I know, do any blending in the shader. When rendering primitive n I want to blend with primitive n-1 which has been rendered, but in the shader I have no access to the pixels generated by earlier primitives. Is the solution to render a primitive (back to front) to a full screen texture and then use that as a reference when rendering the next primitive Should I expect a large overhead from all that texture switching Actually there will be very few primitives. Probably never more than a houn ...Show All

• Visual Basic Help!! Using labels

  Hi- I'm trying to write my first program but I really have no idea what I'm doing. How would you display text on a form without having it appear in a message box I think you would do something with a label but I have no idea how to use it. Also, if I have text in a button that is currently being displayed in a messagebox upon double-clicking on the button, how would I make it so that when you double-click on the button, it appears in a label Thanks!!

• .NET Development Update row SQL and type conversions

  Hi, I'm looking into updating rows using plain SQL statements. I find that I have to convert my data into strings to construct the statement. These conversions need to be mapped to the database types e.g. no comma in a float value. Is this functionality already present somewhere, like it is for reading a record using the many Get... methods in a DataReader Is there a best practice Using DB2, but not looking for a DataSet related solution. Would appreciate your help. Regards, Tonn You have to worry about formatting when using concatentated T-SQL, which is really a bad practice because it opens you up to SQL Injection Attacks.

• Visual Basic prevent tabpage from changing while input is validated

  Greetings: I've got a tabControl with several pages, and the first page presents a summary of the stuff on the other pages. It is set up so that the user input on the back pages is validated on the textbox leave event. A problem occurs when the user goes from entering some invalid text in one of the back page text boxes directly to selecting another tabpage. The validation error messages get shown along with the summary page error messages, and it is not a pretty sight. I tried using a boolean flag in the tabcontrol.selectionChanged event to try to stop the selection change, but that doesn't work. I'm guessing that the selection change event gets fired before the textbox leave event. I've also tried using boolean flags to stop the ...Show All

• .NET Development Microsoft Oracle .NET Data Provider Performance - repeated internal SQL

  Hi, We are noticing several similar SQLs (listed below) which execute many thousands of times per day. The SQL in question does not access any application tables, it accesses the Oracle data dictionary to retrieve metadata, which is essentially static in this context. On one particular day the SQL is issued some 24,024 times, performing 401 million block accesses and consuming 2,080 seconds of CPU. Our concern is that as our transaction rate increases that this SQL may become a performance bottleneck. I'm wondering if there are any configuration settings within ODP or application coding guidelines which may allow the SQLs to be issued once and the results held locally for re-use I have read about connection pooling and statement caching. ...Show All
